Choosing A Spark Plug



Various circumstances such as engine conditions and driving conditions are rough measures for choosing a plug.
For example, if strenuous driving is 
continued for a long time using normal plugs, the plug will overheat. 

This is why the idea of a regular plug for a regular car doesn’t work. What’s important is to inspect the condition of your current plugs, and then choose a plug accordingly.
